Study shows substantial benefits in obese patients after hip arthroscopy
Although obese patients undergoing hip arthroscopy started with lower absolute scores preoperatively and ended with lower overall absolute postoperative scores, they showed substantial benefit from surgery, demonstrating a degree of improvement similar to non-obese patients, according to study results.
Researchers assessed 680 patients undergoing primary hip arthroscopy preoperatively and postoperatively with four patient-reported outcome measures. The researchers estimated pain on the VAS and measured patient satisfaction scores. Five hundred sixty-two patients with a BMI of less than 30 kg/m2 were included in the non-obese group; 94 patients with a BMI of 30 kg/m2 to 34.9 kg/m2 were included in the class-I obese group; and 24 patients with a BMI of 35 kg/m2 to 39.9 kg/m2 were included in the class-II obese group.
Results showed a modified Harris hip score improvement from 63.41 at the preoperative assessment to 83.81 points at the 2-year follow-up visit for the non-obese group, from 54.81 to 75.95 points for the class-I obese group and of 50.81 to 80.01 points for the class-II obese group.
The researchers also found a Non-Arthritic Hip Score improvement of 60.86 to 83.62 points in the non-obese group, of 48.98 to 75.51 points for class-I obese group and of 42.36 to 72.5 points for the class-II obese group.
Within the non-obese group, the Hip Outcome Score – Activities of Daily Living improved from 66.24 to 86.24 points, and the Hip Outcome Score Sport – Specific Subscale improved from 44.01 to 73.26 points from preoperative assessment to 2-year follow-up compared with an improvement from 53.22 to 72.99 points for Activities of Daily Living and from 30.56 to 60.75 points for Sport-Specific Subscale in the class-I obese group and from 48.11 to 74.73 points for Activities of Daily Living and from 28.25 to 62.56 points for Sport-Specific Subscale in the class-II obese group.
Overall, traction time did not vary significantly between groups, according to the researchers. – by Casey Tingle
